Definitions

  • the present invention relates to repellent compositions, in the form of a spray against insects that are vectors of tropical diseases, which are intended to treat textile materials.
  • ECDC European Center for Disease Prevention and Control
  • Dengue fever or yellow fever are diseases transmitted by mosquitoes such as the Aedes species.
  • the World Health Organization (WHO) has seen an increase in the dengue virus in recent years, with more than 40% of the world's population exposed to it. Malaria is transmitted by mosquitoes such as the Anapholes species. These mosquitoes are predominantly present in tropical and subtropical areas.
  • repellent protection is a strategy of choice. Indeed, repulsion makes it possible to avoid the bites of these insects, and thus the proliferation of the aforementioned tropical diseases. Therefore, there is a continuing need for improvement of repellent compositions against insects, vectors of tropical diseases.
  • Repellent compositions may be in various forms such as sprays, lotions, wipes and sticks for application to the skin to protect it from insects bearing tropical diseases.
  • Known spray repellent compositions often include active repellent ingredients such as permethrin or essential oils which are dissolved in a solution.
  • the present invention remedies all of these drawbacks by proposing a novel repellent composition against insects, vectors of tropical diseases such as mosquitoes in the form of a spray and which is intended to impregnate a textile material to give it a repellent effect perfectly effective and durable over time.
  • the inventors of the present invention have in fact developed a novel repellent composition in the form of a spray by selecting specific repellent active ingredients which are also microencapsulated in such a way that they are progressively released during the course of time as to increase the protection time of the textile material relative to that of textile materials impregnated with other repellent compositions in the form of a spray.
  • the microcapsules of the repellent composition according to the invention comprise a core containing the aforesaid repellent active ingredients, the core being coated with a membrane.
  • the first subject of the present invention is a repellent composition against insects, vectors of tropical diseases, such as mosquitoes in the form of a spray which comprises at least:
  • microencapsulation of the aforementioned active repellent ingredients has the advantage of protecting them thanks to the membrane and of releasing them only when the membrane is burst. This is why the aforementioned encapsulated active ingredients retain their repellent properties for long periods of time.
  • the release of the active ingredients contained in the core of the microcapsules is achieved by rupturing the membrane of the microcapsules following a mechanical process such as friction, rubbing, shearing or scraping.
  • a mechanical process such as friction, rubbing, shearing or scraping.
  • it may be a friction created by wearing the garment treated with the repellent composition or a piece of bedding and its contact with the skin or by rubbing the textile material treated on any surface of contact (e.g. furniture, skin).
  • the textile materials treated with the repellent composition according to the invention have a lasting repellent effect against insects, vectors of tropical diseases, even after several years of storage (at least 3 years) if there has been no rupture of the membranes of the microcapsules by a mechanical process as detailed above.
  • microencapsulation enables the fixing of active ingredients on to the textile material via the microcapsules.
  • the active repellent ingredients contained in the repellent composition according to the invention have the advantage of being protected against harmful external influences such as light, bacteria, chemical modifications of the environment (e.g. pH, presence of water).
  • binding agent is understood to mean an agent which allows the microcapsules to be attached to the textile material.
  • binding agents of microcapsules on a textile material are within the purview of those skilled in the art.
  • wetting agent means an agent which ensures the wettability of the repellent composition on the textile material.
  • the microcapsules contain, based on the total mass of the active ingredients that they contain:
  • the core of the microcapsules contains essential oil of lemon eucalyptus. Indeed, this essential oil contains p-menthane-3,8-diol. Thus, in one embodiment of the invention, the core of the microcapsules comprises at least the essential oil of lemon eucalyptus and lavandin essential oil.
